From Hydration to Vibration: DJ Big Gulp’s Evolution from humble Gatorade jug to seaworthy Bluetooth speaker

To put this into context, I took my first Loopy’s tubing trip long before waterproof Bluetooth speakers were something you could just go pick up at your local Circuit City. For the average rivergoer, a tranquil float down the serene Chippewa River on a beautiful sunny day is already pretty hard to beat. But what kind of engineer would I be if I didn’t seize the opportunity to enhance such a natural experience with a piece of cobbled together tech designed for the sole purpose of blasting out the fattest bangers of 2005?

Since the Cutlass was already an extremely high-performance machine, and that fact that I know next to nothing about auto mechanics, the upgrades were purely electronics related. CarPlay The first order of business was to hack in an aux input into the radio, which only Continue Reading
